Paul; here are a few questions that you need to answer before you can make a decision as to how you will sell your product/service:
1. to whom are you selling? : i.e. who do you believe is your ideal prospect?
1.1 are you targeting consumers or businesses?
1.2 if b2b then what size?
2. what is the value of a typical sale: LTV or NPV?
Answers to the above will help you quickly decide whether the numbers will even pencil out to support a direct sales model. I would not recommend going directly to a channel sales model at this stage as you just don't have enough history yet to know what works and what doesn't and how to direct, train, motivate and compensate your channel partners. You can back into the numbers starting with what a 'good' direct sales person in your industry makes in salary and commission. If you are not offering a base salary to supplement commissions then you need to ad a "ramen noodles multiplier', i.e. 'here's how we will sweeten your comp plan to make up for the fact that you will likely starve until commissions start coming in". Since you are a startup with presumably limited resources then you need to add a "risk multiplier", i.e. the sales person will have to wear a lot of hats until THEY produce the revenue to allow the company to offload some of the work such as: marketing, sales/demo materials, sales scripts, CRM/opportunity management tools, on-boarding support, etc. Until such time the sales person will have to consume valuable selling time with some of the above activities. If this sales person does not have significant experience and expertise and contacts in your industry then there is a learning multiplier too.
i don't know the music business so here's a very rough example using SaaS sales in the tech industry - say you are selling CRM or ERP systems B2B for example. A "good", not great, not top performer, but not a rookie either sales rep will be expecting to make $150-$200k at target including a base of say, $60-$70k so commission = $80 - $140k. A mature company might pay 15%-20% of the NPV of a sales in commissions, funded startups will likely pay more to allow for the lack of industry name recognition, perceived risk by customers, competitive barriers to entry, etc. Unfunded startups will need to pay even more - let's 30-35%. So lets say you are an unproven startup with no funding and limited resources and you are not selling in/to the music industry, but instead selling SaaS services to large B2B prospects: $150-$200k/yr @ 30% commission = $500,000 - $667,000 in paid revenue (assuming you can't afford to pay commissions until cash actually hits the company's bank account). Add in the risk and ramen and ramp-up multipliers and you are looking at more like 2-3 X these numbers. I would assume that not all contracts will be paid up-front so that will affect revenue recognition as well as cash on hand to pay commissions - adjust accordingly. So if your sales person sells only your $29.00/month package that would pencil out to somewhere between 1,437 - 1,917 transactions/yr = 120 -160/month = 30-40 transactions/week = 6-8/day = about 1/hr.... 2x - 3x or more considering the multipliers. You might be able to address some or perhaps all of the risk multipliers with some equity arrangement. It looks to me like these numbers simply won't pencil out if you want this person to sell your current offering at your current pricing. Your sales person would be better utilized working on larger B2B deals if that is even feasible with your product. And of course it may be possible to attract a 'good' sales person at a lower total comp plan too, but i doubt it would be .5x the above example.
so before you run out and start spending time trying to recruit a sales person you have some work to do to make the numbers work. You will need to be prepared to share your math with prospective candidates too.
